Materials Assigned to Walls
When setting up a problem in Fluent, there are materials assigned (automatically) to the walls, even though the walls have thickness of zero. I believe these material setting is not critical, i.e., I won't need to change them from the default (it seems to be aluminum, or another material I have used somewhere in my model). Can someone please confirm if my assumption is correct? (or let me know if I am wrong).

It depends on your simulation.
for instance It might be used if you are accounting for thermal inertia in your case.

Yes, If you keep wall thickness equal to zero it is neglected in calculations and material doesn't matter.
